The World's Largest Carbon Removal Project Yet Is Headed For Wyoming (theverge.com) 76

A couple of climate tech startups plan to suck a hell of a lot of carbon dioxide out of the air and trap it underground in Wyoming. The Verge reports: The goal of the new endeavor, called Project Bison, is to build a new facility capable of drawing down 5 million metric tons of carbon dioxide annually by 2030. The CO2 can then be stored deep within the Earth, keeping it out of the atmosphere, where it would have continued to heat up the planet. A Los Angeles-based company called CarbonCapture is building the facility, called a direct air capture (DAC) plant, that is expected to start operations as early as next year. It'll start small and work up to 5 million metric tons a year. If all goes smoothly by 2030, the operation will be orders of magnitude larger than existing direct air capture projects.

CarbonCapture's equipment is modular, which is what the company says makes the technology easy to scale up. The plant itself will be made of modules that look like stacks of shipping containers with vents that air passes through. At first, the modules used for Project Bison will be made at CarbonCapture's headquarters in Los Angeles. In the first phase of the project, expected to be completed next year, around 25 modules will be deployed in Wyoming. Those modules will collectively have the capacity to remove about 12,000 tons of CO2 a year from the air. The plan is to deploy more modules in Wyoming over time and potentially manufacture the modules there one day, too.

Inside each of the 40-foot modules are about 16 "reactors" with "sorbent cartridges" that essentially act as filters that attract CO2. The filters capture about 75 percent of the CO2 from the air that passes over them. Within about 30 to 40 minutes, the filters have absorbed all the CO2 they can. Once the filters are fully saturated, the reactor goes offline so that the filters can be heated up to separate out the CO2. There are many reactors within one module, each running at its own pace so that they're constantly collecting CO2. Together, they generate concentrated streams of CO2 that can then be compressed and sent straight to underground wells for storage. DAC is still very expensive -- it can cost upwards of $600 to capture a ton of carbon dioxide. That figure is expected to come down with time as the technology advances. But for now, it takes a lot of energy to run DAC plants, which contributes to the big price tag. The filters need to reach around 85 degrees Celsius (185 degrees Fahrenheit) for a few minutes, and getting to those kinds of high temperature for DAC plants can get pretty energy-intensive. Eventually, [...] Bison plans to get enough power from new wind and solar installations. When the project is running at its full capacity in 2030, it's expected to use the equivalent of about 2GW of solar energy per year. For comparison, about 3 million photovoltaic panels together generate a gigawatt of solar energy, according to the Department of Energy. But initially, the energy used by Project Bison might have to come from natural gas, according to Corless. So Bison would first need to capture enough CO2 to cancel out the amount of emissions it generates by burning through that gas before it can go on to reduce the amount of CO2 in the atmosphere.
"The geology in Wyoming allows Project Bison to store the captured CO2 on-site near the modules," adds The Verge. "Project Bison plans to permanently store the CO2 it captures underground. Specifically, project leaders are looking at stowing it 12,000 feet underground in 'saline aquifers' -- areas of rock that are saturated with salt water."

    So is it getting subsidized somehow ?

    This is fucking idiotic.

    Really, how is it that anybody thinks this is worth the money ?

    • It makes some sense as an R&D project since we will need to eventually do DAC to get CO2 back down.

      But there is no reason to do it now, since we won't need it for decades, and there is no reason to do it on such a large scale.

      So, yes, this is really stupid.

      The big question is: Cui bono? Who is profiting from this insanity? How? Why?

      At first, I assumed the CO2 was going to enhanced oil recovery [wikipedia.org], which would make much more economic sense. But according to TFS, that is not the case.

      Currently liquid carbon dioxide sells for about $365 per metric ton. So they are in shooting range of being able to sell it at a profit, which would be a lot easier than pumping it underground.

      • Ah, but then it wouldn't be captured. Those consumers use it for fizz, animal stunning, ... but in all those cases, it is released, so wouldn't qualify for the much more lucrative carbon capture money. Interestingly, the shortage of Nat Gas has caused a shortage of CO2 for just those purposes in the UK. https://www.theguardian.com/bu... [theguardian.com]
      • One would assume that increasing the production of CO2 by several orders of magnitude ( which must be their goal, to have any effect on global warming ) would have a correspondingly large effect on the market price of CO2.

        Nope, it's just a stupid diversion from cutting CO2 emissions by getting fat bastards out of their cars:

        So they are in shooting range of being able to sell it at a profit, which would be a lot easier than pumping it underground.

        The obvious problem there is that the result is no longer captured and sequestered but rather released back into the atmosphere by other means.

        The cost of liquid CO2 is what the market will bare, nothing more. CO2 is largely produced as a waste stream from other industrial sources and doesn't follow a traditional free supply and demand curve. If these guys come in with a cheaper product then the traditional producers of CO2 will just drop the price since they are doing it for cost recovery rather than being a profit centre. DAC cannot compete with traditional CO2 production in this regard.

        By the way the current CO2 market is heavily distorted. The cost of $365/tonne is not normal and about 3x higher than usual this year.

    • Short answer, yes, 85 bucks/metric ton. https://www.bloomberg.com/news... [bloomberg.com] I believe it was already getting the carbon credits that companies were buying, but it is such a confusing mess, I can't keep track anymore. I have no doubt if they are spending 600/ton to do the capture, somehow they are getting a grand a ton to do it. What is particularly insane about this is they are going to burn fossils to capture carbon. Insane.
    • It'll start small and work up to 5 million metric tons a year

      That's like removing one drop of water from the ocean.

      DAC simply cannot scale up big enough to remove a *SIGNIFICANT* amount of carbon and do it at anything even remotely near a reasonable price. This is another pointless boondoggle.

      • It'll start small and work up to 5 million metric tons a year

        Carbon emissions are currently estimated to be 35 billion tons of carbon dioxide (9.5 billion tons of carbon) per year.

        Get out your calculator. 5 million is ____ percent of 35 Billion.

        Hint: It's a really, really, really small number.

      I am not an expert, but it's difficult to see how this can be a more economical capture strategy than growing and burying biomass. e.g Locally I can get a 4x5 round bale of hay for $50 that weighs about 800 pounds. Spitballing that you'd need 5 of those for a ton of CO2, that's still leaves a lot of headroom to cover the cost of digging the hole and burying it. ... not that you'd have to use a good product like hay. Slab wood from sawmills is (or used to be) cheaper than that.

      • Planting trees and then making durable wood products from them has a *negative* cost per ton. Planting seedlings is very cheap in bulk, and mature trees fetch a decent price in lumber, plywood, etc. Just make sure the houses and furniture you make from it will last, not particleboard junk that ends up in a landfill and decomposes.

        So as a society, we should be encouraging as much tree planting as possible before investing in other carbon capture schemes.

    • It's not a good solution to the overall problem - it's not like we can just continue business-as-usual and just add carbon capture. It's also not a good cost/benefit for reducing carbon emissions in the short term. But there are segments of the economy that are important, but also emit a lot of CO2. For instance, concrete production and curing emit CO2 as part of the chemical process, even if you used all renewable energy. There are a lot of other segments that are not impossible to decarbonize, but are d

      I know right, it's like you didn't even realise this is a pilot plant nor read the middle sentence you quoted.

    • Here's a question: If all goes according to their most optimistic estimates & they can meet their efficiency targets, develop the technology, build the GWs of power stations, find the funding, & "scale up," how long would it take them to make a dent in the 35 billion tonnes of CO2 emitted each year?
    • It's really hard to believe that this is a better use of time and resources than just continuing to improve and expand the renewable energy infrastructure.

      Or for an even better use of time and resources, use of biological carbon sequestration, such as ocean seeding with nutrients to promote the growth of carbon-eating alga and plants. Do this in the Atlantic or Pacific gyre, and plant life that sinks to the bottom after the nutrient is used up could also entrain that ever-popular floating plastic.

    ... and it's in Wyoming, so that energy will come from burning coal.
    • From natural gas. At least, according to the summary.

    • ... and it's in Wyoming, so that energy will come from burning coal.

      Wyoming, eh? Lot of open space. Not exactly tropical. Perhaps we move Arizona there and replace that facility with a few million homes instead?

      We do little to nothing about the problem, and we're going to eventually have to start relocating humans if we intend to keep them alive. (Greed in real estate will fight this worse than tobacco fought cancer. Be prepared.)

      If all goes smoothly by 2030, the operation will be orders of magnitude larger than existing direct air capture projects.

      Let's hope orders of magnitude will be enough to validate the project one way or another. You know, before the coal industry lobbies to cut

      What happens when the storage leaks?

      The CO2 is pumped into geological formations that held methane for millions of years. Methane is much more geologically mobile than CO2.

      Under pressure, CO2 forms a super-critical fluid denser than water, so it will sink beneath the saline layer.

      This is a stupid project, but leaks aren't a problem.

      That is nothing like this project. It was methane, not CO2, injected into a temporary storage well, not a deep saline layer.

  • Specifically, project leaders are looking at stowing it 12,000 feet underground in 'saline aquifers' -- areas of rock that are saturated with salt water."

    Sure. Until some enterprising official who didn't get paid off "discovers" an obscure amoeba in the aquifers. Then cue the lawsuits to "protect the delicate habitat".

  • An average car emits 4.6 metric tons At $600/ton that means we are spending $2760 per car each year for this. The number of cars on the road during the pandemic decreased by millions If more companies made work from home available then we wouldn't need these plants at all.

  • We still pump CO2 from the Jackson Dome [wikipedia.org]. Maybe we should stop pulling carbon out of the ground before we play around with putting it back in. You'll never be able to put it in faster than we can take it out. And it's not clear how permanent these experimental carbon capture techniques will be.

      You would need to plant about four million hectares to (temporarily) absorb the tiny amount this DAC plant would capture.

      Trees are nice. I like trees. But they will never offset a non-negligible percentage of CO2 emissions.

      It was on a Ford Expedition.

      • A mature forest absorbs no net CO2.

        This is completely, literally, spectacularly wrong. It is in fact literally backwards. You have not the foggiest notion how a tree works.

        • I think they are referring to as trees die and decay, they re-emit most of their stored CO2. How much net storage happens depends on soil building/erosion processes.

      • > A mature forest absorbs no net CO2.

        It does if you harvest the mature trees, turn them into durable wood products and replant. Municipal sludge, the stuff removed by water treatment plants, can be used to fertilize the trees replanted, if the natural soil gets too depleted on its own.

          It would require approximately doubling the number of trees in the USA, and logging twice as much as now to absorb the USA's current emissions. It's a lot of trees. I don't know if there is a market for that much lumber, but possibly. Many countries could not hope to do this. The Netherlands doesn't have the space unless they make a lot more The Netherlands, for example. Trickier for Switzerland.
